The Pi Cycle Top indicator is composed of the 111 day moving average (111MA) and a 2x multiple of the 350 day moving average (350MA x 2) of Bitcoin's price.
The Pi Cycle Top Indicator is a highly accurate indicator for picking the tops of Bitcoin’s market cycles. For the last three cycles it correctly identified the top to within 3 days.
This metric shows when BTC becomes significantly overheated (the 111MA reaches the levels of the 350MA x 2), and has historically been a good indicator for cycle tops. This metric was first put forward by Philip Swift.
Pi Cycle Top indicator = 350MA * 2 and 111MA
